INDEX.

Application filed July 26, 1917.

T 0 all whom it may concern:

Be it known that I, JAMES H. RAND, a citizen of the United States. and resident of Newton, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Indexes, of which the following is a specification.

This invention relates to a card ledger or card index of the so-called visible type wherein a series of cards or sheets are supported in a vertical frame in overlapped relation with their margins exposed to display names or other index matter or identifying inscriptions.

In the accompanying drawings, lwhich illustrate one embodiment of the invention,

Figure 1 is a face View of a part of a ledger or index embodying the invention, parts being broken away;

Fig. 2 is a face View of one of the holders for a card or sheet;

Fig. 3 is a plan view of said holder;

Fig. 4: is a perspective view of a complete index unit or ledger unit, including the holder and the sheet or card;

Fig. 5 is a vertical section of the unit shown in Fig. t; and

Fig. 6 is a plan or face view of such unit with the sheet unfolded. e

A represents the body oft-he usual frame, which may be made of sheet metal or other suitable material, with inturned flanges a at its opposite edges to form inwardly facing channels for receiving the ends of the card or sheet holders.

Each holder comprises a rail B, which may consist of a strip of paper material such as bristol board or leather board, or other suitablematerial, which should preferablv be sufficiently resilient to admit of its being shortened by bending the central part away from the frame so that the ends may be inserted into the channels formed by the flanges a. A hanger C, also made of flexible or resilient material, such as a length of wire. extends lengthwise of the rail and is secured at its endsthcreto. In the form shown. the wire hanger C has its ends bent over to pass through and engage perforations b in the rail B, said ends being clenched down upon the rear side of the rail as shown at c. The length of the wire hanger C and t-he'points of attachment thereof to the rail B should be such that the ends of the rail B are left free of ob- Specification of Letters Patent.

structions or projections which would interfere with the proper insertion of the ends of the rail into the channels of the frame and of their sliding lengthwise of said channels. In other words, the ends of the hanger are secured to the rail at points removed from the ends of the rail.

Supported on each hanger is a card or sheet D, passing between the rail and hanger and folded over the hanger along the fold to form two depending leaves (Z and cl. Notches (Z are cut out at each end of the fold (Z adjacent to the bent over ends of the wire hanger. Said notches serve both to prevent the dislodgement of the sheet from its hanger, holding it properly in place on the wire C, as on a hinge, and also enable a sheet or card to be used of the full lateral breadth of the frame, notwithstanding the hanger terminates short of the rail.

The vertical length of one. of the leaves preferably exceeds that of the other leaf, with the result that when a series of units are mounted in the index frame in overlapped relation, as illustrated in Fig. 1, each double leaf sheet will have but a single projecting index margin. In the preferred form the under leaf (l is longer than the front leaf (1, thus leaving the index margin of the under leaf exposed to view both when the sheet is hanging normally as shown in Fig. 1, and when the front leaf (Z is folded back, flattening the sheet out as shown in Fig. 6, for inspection or the making of entries. This exposed margin will preferably be protected againstsoiling or injury by manipulation by a celluloid sheath E secured to the lower edge of the leaf (Z. The sheath E may be attached by the rearwardly folded section e and infolded lip e which engage the rearwardly folded edge (Z of the leaf. The face-of the sheath E fpreferably extends far enough up over the ace of the leaf (Z so as to cover the entire exposed margin and to terminate above the lower edge of the front leaf (Z', thus avoiding any danger of the front leaf (1 from catching on the edge of the sheath E.

It will be'understood that the sheet D is readily removable from its holder; that it may be properly ruled, entitled, or otherwise prepared for the entries for which the device is to be used; that being merely folded over the wire hanger without pasted or slotted hinge members it is adapted'to be unfolded into a smooth flat sheet for being slide in an index frame and a hanger extending lengthwise of the rail and held at its ends thereby, both rail and hanger being made of flexible material whereby 1nsertion in the frame can be effected by bending both the hanger and rail.

2. A holder comprising a rail of flexible resilient material having ends adapted to slide in an index-frame, and a wire hanger extending lengthwise of the rail and held at its ends by the rail, the rail and hanger being adapted for bending for insertion in the frame.

3. A holder comprising a rail of flexible material having apertures near its ends, and a resilient wire hanger extending lengtlr wise of the rail, having its ends bent to pass through said apertures, and clenched 011 the rear side of the rail.

4. An index device having a channeled frame and a holder therein comprising a rail having an aperture near each end and a wire hanger extending lengthwise between said apertures, having its ends bent to engage said apertures and mount the wire hanger on the rail, the holder being adapted to slide in the frame.

5. A holder comprising a rail and a hanger extending lengthwise of the rail and engaged at it ends thereby, and a sheet folded over and supported by said hanger, the rail, hanger and sheet being flexible to permit insertion of the holder in a channeled frame.

6. A holder comprising a rail and a hanger extending lengthwise of the rail the ends of the hanger engaging the rail at points removed from the ends thereof, and a sheet folded over and supported by said hanger; rail, hanger and sheet being flexible to premit insertion of the holder in a channeled frame.

7. A holder comprising a flexible rail and a resilient wire hanger extending lengthwise of the rail and secured at its ends thereto. and a sheet folded over and supported by said wire hanger, the assembled structure being adapted to form an element of an overlapping visible index when inserted in a suitable frame.

8. A holder comprising a rail having a perforation near each end, a wire hanger extending lengthwise between said perforations, having its ends bent inwardly to engage said perforations and to secure the wire hanger to the rail, and a sheet folded over and supported by said wire hanger, space for insertion of the sheet being provided between hanger and rail.

9. A holder comprising a rail, and a hanger extending lengthwise of the rail and secured at its ends thereto, and a sheet folded over and supported by said hanger, said sheet having notches at the ends of its fold.

10. A holder comprising a rail having a perforation near each end, a wire hanger extending lengthwise between said perforations, having its ends bent to engage said perforations and secure the wire hanger to the rail, and a sheet folded over and supported by said wire hanger, said sheet having notches at the ends of its fold adjacent to the bent ends of the wire hanger.

11. A holder comprising a rail and a hanger extending lengthwise of the rail and secured at its ends thereto, and a sheet folded over said hanger to form two depending leaves, the vertical length of one of which leaves exceeds that of the other.

12. A holder comprising a rail and a hanger extending lengthwise thereof and secured at its ends thereto, and a sheet folded over said hanger to form two depending leaves, the vertical length of the under leaf exceeding that of the front leaf.

13. A holder comprising a rail and a hanger extending lengthwise thereof and secured at its ends thereto, and a sheet folded over said hanger to form two depending leaves, the vertical length of the under leaf exceeding that of the front leaf, and a celluloid sheath attached to the lower edge of the under leaf and covering that portion of the under leaf which projects beyond the front leaf.

14. A frame having inwardly facing channels. a series of holders, each comprising a rail having its ends mounted in said channels and a hanger extending lengthwise of the rail and secured at its ends thereto at points outside of said channels, and a series of sheets folded over and supported by said hangers respectively, one leaf of each sheet being shorter in its vertical dimension than the other.

15. A frame having inwardly facing channels, a series of holders, each comprising a rail having its ends mounted in said channels and a hanger extending lengthwise of the rail and secured at its ends thereto at points outside of said channels, and a series of sheets folded over and supported by said hangers respectively, the front leaf of each sheet being shorter in its vertical dimension than the under leaf.
